Ruger SR762 - Failure to Feed. Need help

With those pictures it does look like burrs on the feed ramp, although it seems like quite a specific problem with the third round.

With the magazine itself, if you load it up to 5 rounds and try and strip them out (by hand) quickly, does the follower hang up around that third shot area? It could be the rivet is too long on the mags you have (not uncommon, several of my UMP45 mags had the rivet about 1/8th inch too long and the spring would hang up)

If the mags seem to feed properly, then my guess is that's the feed ramps jamming up the third shot... Maybe see if you can try a nice round nose bullet and see if that helps any? (just for testing) and if that seems to work, then a feed ramp polish may be what it's looking for...

Good luck, getting spare parts and repair for Ruger is not very easy...

First thing I thought about too that it could be the mag. The thing is I bought two of this rifle and was able to compare and swap magazines between the two. The other rifle do not exhibit the same FTF issue and so ruled out the mags (DPMS and Gen 3 Pmags).
 
Last week at the range and using Norc and Federal GM rounds, the same FTF was duplicated (see post #1). Luckily, a fellow CGNer was there to assist in trying to further this along. Tried to duplicate the issue by slowly charging and releasing the bolt and observe the bolt and round behaviour. The FTF was duplicated and this is what it looked like when the bolt is in contact with the round.

This is a screen grab from the video and you can see the bolt tip barely touching the round (red arrow). It is suspected that due to the small surface contact, the bolt and round can slip off (specially at high speed) and cause the bolt to ride over the round while the round is at the feed ramp. This results into the FTF and rounds seen in post #1. That is the thought around this and has been shared with the repair center.
 
Well if it's any consolation, I went through Ruger warranty process for my 1911 and it was great.
Great communication and they got it sorted out as quickly as possible. They exchanged my 1911 and sent me a new one with all the accessories, mags, etc.

Hopefully they will replace your rifle if worst comes to worst.

Humm, wonder if it's just the mags not being able to seat in deep enough. In the pic above, you were manually cycling the bolt? Maybe bad milling of the mag catch location and it is just out of spec? If you push up on the mag or shoot with the mag acting like a monopod, does it cycle reliably?

Yes it was manually cycling the bolt. Interesting observation and it does look like it maybe the issue. I won't be able to try it out soon as its packed for Quebec. I will relay that info and for them to try. I hope this is it. Thank you for that!

Swap out the lower and upper between both of your rifles and see if one of the two will FTF, then by process of elimination try and determine if it's one of the upper or lower that's out of spec. The bolt is barely stripping that round so that Trinimon said is what is most likely causing that FTF, you just need to know which half is off.

Good luck!
 
Update from the repair center.

After much correspondence and pictures between snapshot and Ruger, Ruger has determined that the upper and lower receiver need to be replaced. But more hurdles to come. While in the process of preparing the parts shipped to Canada, Ruger realized that the SR762 is not a rifle they sell in Canada. What this means is that while snapshot is licensed to receive parts and repair for any firearms Rugers sell in Canada, not the SR762. So more hurdles here for the repair center and more wait for me. Snapshot will need to apply for a license (Canada and US) to receive the SR762 parts from Ruger. This can easily take another 1-2 months. A guesstimate would have the SR762 back to me sometime in December assuming no other surprises come up.
 
Thanks for the update. I didn't know that the SR762 wasn't shipped up to Canada. Who did you get yours from? I'm reading about another SR762 owner on the Ruger forum with one of the newer serial numbers having similar issues.
 
Well this is a mess!! Did you buy it from IRG? This question is of great Interest as they have stated they would take care of all warranty issues for the gun they sell in Canada. So I can't wait to here if it's from them as I have bought a gun from them and this may affect latter purchase.

Thank you and sorry for your trouble.

From IRG on Jan or Feb of this year.
 
I was strongly considering this rifle until this thread. It is really unfortunate that the support measures on this side of the Border are not able to resolve this or at the very least exchange your rifle for a replacement.

I hope you get a running firearm soon and can share the issue with us and the Ruger will take care of you.

Thanks for sharing this.
 
I am not one for dealer bashing, but I do believe that dealer needs to stick to there words and I am really disappointed in IRG .

Please steel cap for u and all of us who bought or are thinking of buying from IRG please start a tread on there forum. And I will stick to my guns if they don't help you they won't see any more money from me!

They've made multiple claims in many threads that they will look after warranty for everything they sell.
 
Ship it back to the importer, these are the costs of selling firearms, they will have to take care of it for you.
If ruger themselves are saying that there is a problem, its up to the importer to handle the repair.
